Male infertility: low sperm count and what helps
In about half of couples who struggle to conceive, a male factor plays a part. It is common, it is nobody's fault, and in most cases something can be done. Male fertility is one of Dr. Brahma's special interests.
Reading a semen report
| Measure | WHO lower limit |
|---|---|
| Volume | 1.4 ml |
| Concentration | 16 million per ml |
| Total motility | 42% |
| Progressive motility | 30% |
| Normal forms | 4% |
One abnormal report is not a diagnosis. Fever, illness and stress can lower the numbers for weeks, so a second test is done 6–12 weeks later before any decision.
Common causes
- Varicocele (enlarged veins in the scrotum)
- Smoking, heavy alcohol, obesity, anabolic steroids or testosterone supplements
- Heat: hot baths, laptops on the lap, long hours of driving or sitting
- Past infections such as mumps orchitis, or sexually transmitted infections
- Hormone problems, undescended testes in childhood, genetic causes
- Blockage of the sperm ducts (in obstructive azoospermia)
What helps
- Stop smoking and cut alcohol. Reach a healthy weight. Avoid heat.
- Never take testosterone or bodybuilding supplements while trying for a baby: they can stop sperm production completely.
- Treat infections and hormone problems.
- Varicocele repair in selected men with a clear varicocele and abnormal semen.
- IUI for mild problems; ICSI for moderate to severe ones.
- Surgical sperm retrieval (PESA, TESA, micro-TESE) with ICSI for azoospermia.
Questions
Can a man with zero sperm count become a father?
Often, yes. If sperm is being made but cannot get out, it can almost always be retrieved with a needle. Even when production is very low, sperm can be found in a proportion of men by micro-TESE. Hormone and genetic tests guide the plan.
Do supplements improve sperm count?
Antioxidants may help a little in some men, but the evidence is modest. Stopping smoking, losing weight and avoiding heat do more.
